Process and product for application for preserving metallic products from corrosion

ABSTRACT

The subject invention is a process for preserving metallic products from deterioration from corrosion or oxidation, comprising the application of a protective product including the following the steps of applying,  
     (a) cleaning the exterior of the metallic product of removing scaling or other externally disposed by products of corrosion;  
     (b) applying a corrosive removal substance comprised of water, ammonium components, alcohol and a solvent premix which is in turn comprised of alcohol and mineral spirits.  
     The subject process may include the further process of painting the surface of the metallic surface after the above described anti-corrosive substance is applied and in some cases removed.

DISCUSSION OF PRIOR ART AND BACKGROUND OF THE INVENTION

[0001] The invention which is the subject of this patent application isdirected to a process for protection of the exterior of a metallicproduct from corrosion, such as oxidation resulting in rusting of themetallic surface or exterior.

[0002] The general area of focus is directed to means to cover theexterior of the product from oxidation or other chemical reactions thatcause the surface to be corroded. Another focus of the subject inventionis to remove rust, or other corrosive by-products from the exteriorsurface of a metal.

[0003] In short the subject process herein described is adapted to bothprotect and shield a metallic surface from corrosive activity, as wellas clean and remove from the metal surface already existing corrosivesubstances. The latter cleanser process may be utilized to precedepainting on the metallic surface as an additional protective layer;

[0004] In the perspective and context of the subject invention, as isknown, metallic surfaces are invariably subject to and susceptible tocorrosive processes, in which the metallic surfaces reacts chemicallywith the surrounding elements, most usually oxygen. These reactionsresult in differing chemical reactions and thus varying chemicalprocesses, generally referred to as corrosive reactions leaving a layerof corrosive material on the outer surface of the metal. One of the mostfrequently encountered corrosive processes is oxidation of ironresulting in a layer of iron oxide, commonly referred to as rust.

[0005] These described corrosive processes leave the metallic surfacesusceptible to deterioration and if left long enough causes deeperpenetration of the corrosion into the metallic object, causing aneventual weakening and deterioration of the entire metallic object. Thismay adversely affect other interconnected systems or structures. Forexample, if one portion of an iron-based bridge structure becomesubstantially weakened the entire bridge integrity and strength isadversely affected. Thus, rust protection and rust proofing of allintegrated metallic sub-structures of a bridge is one of the mostimportant aspects of maintaining the bridge.

[0006] There have been innumerable processes and products concerned andused since the advent of man's use of metallic substances for protectionagainst corrosion. Some of these products have been directed to thesimple process of removing a rust or corrosion covered surface, whileothers have been addressed to solely a protective function. Otherproducts have evolved that are directed to both functions, with someemploying expensive chemical or other processes and products. A numberof these products have been found to be cumbersome in use, while othershave not been effective as a means for quick and effective removal ofsuch existing rust or corrosive coverings.

[0007] The subject invention is conceived as an improvement over theexisting products and processes that are used in this general areaConsequently, the subject invention is directed as a specificimprovement over the general area of products and processes used in thisregard. Accordingly, the following objects of the subject invention aredirected accordingly.

[0009] It is object of the subject invention to provide an improvedprocess for protection metallic surfaces from corrosion.

[0010] It is also an object of the invention to provide means to shielda metallic surface from rust or other corrosive processes.

[0011] An additional object of the subject invention is to provide animproved method of shielding a iron based structure from rusting .

[0012] A further object of the subject invention is to provide animproved method of removing corrosive products from a metal surface.

[0013] Yet another object of the subject invention is to provide animproved product for removing rust and/or corrosion substances from ametal surface.

[0014] A further object of the subject invention is to provide animproved method of preparing a metal surface for painting.

[0015] Still another object of the subject invention is to provide meansto protect a metal surface from deterioration.

[0016] Other and further objects of the subject invention can be seen inthe following description and claims read in view of the drawingsherein.

DESCRIPTION OF GENERAL EMBODIMENT AND SUMMARY OF INVENTION

[0017] In the most general form of the embodiment of the subjectinvention, the process in this case involves the following general stepsas an overall basis for implementation of the subject invention.

[0018] (a) clearing the rough scales and corrosive substances;

[0019] (b) applying a corrosive removal substance comprising generallyof water, ammonium components, alcohol and a solvent premix which iscomprised of alcohol and mineral spirits;

[0020] The subject process may include the further process of paintingof the surface of the metallic surface after the above describedanti-corrosive substance is applied.

[0021] It is to be stated that the above process and above discussedsubstances can be used on all types of metallic substances and may beapplicable to all types of corrosion on any type of metallic surface.

DESCRIPTION OF PREFERRED EMBODIMENT

[0022] In describing the preferred embodiment of the subject inventionit is to be stressed that the following description is only of onespecified embodiment of the invention. In so describing a specifiedembodiment no limitation on the scope of the subject invention will beconstrued as a result. Further, in describing the subject invention andthe components of the anti-corrosive substance it is to be understoodthat the individual components, as specifically delineated, may includeother compounds or elements that fall within the same general chemicalclassification for such specific product. If such substitute substancesare not specifically described it shall not limit the scope of theinvention and the claims herein

[0023] In the most general form of the embodiment of the subjectinvention, the process in this case involves the following general stepsas an overall basis to implementation of the subject invention.
